We had no friends in Silverado, except for a Jewish couple in their eighties whom my mother met at the supermarket, or so she told me, and whom we saw every three or four days, just for a few minutes and always at their house. According to my mother, it was our duty to visit them, because old people could have an accident or one of them might die all of a sudden and the other one might not know what to do, something I doubted since the old people had been in a German concentration camp during World War II and were hardly unacquainted with death.
